Maxillari/ palpi, very short aud iuconspiciious. 



Tougiie, very long, clothed with scales ouly at the extreme base. 



OceUi, absent. 



Head, smooth. 



Fore- wings, elongate, sharply lanceolate, the costa slightly bulged before the middle ; 



11 veins ; 3 aud 4 from a common stem ; 7 and 8 from a common stem, the lower 



branch running to the apex, the upper to the costa. 

 niud-icings, elougate-lanceolate, sharply pointed, the costa arched before the middle, 



the abdoraiual margin somewhat widened aud depressed. 

 Abdomen, geuital segments of ^ largely developed; the uncus and lateral claswers 



tapering posteriorly ; the points, slightly upturned, extending three-sevenths of 



the whole length of the abdomen ; the ovipositor of the 9 extruded. 



Arotrura ebiirnea, sp. n. 



Antemuv, ivory-white ; basal joint elongate, flattened at the base, and slightly 



arched. 

 Palpi, ivory-white ; clothed with appressed scales, which are somewhat dilated down- 

 wards on the basal joint only ; apical joint about two-thirds the length of the 

 second, somewhat less stout, but by no means slender. 

 Tongue, very loug, clothed at the base with ivory-white scales ; beyond, naked, 



light yellowish-brown. 

 Head, face, and thorax, smooth ivory-white. 



Fore-wings, elongate, sharply lanceolate, ivory-white; cilia, ivory-white. 

 Hind-tcings, pale grayish-fawn ; cilia pale fawn at their base, fading outwardly into 



fawn-white. 

 Under side of fore and hind wings, tinged with grayish-fuscous in the <?, tending to 



pale fawn color in the 9- 

 Abdomen, ivory-white; somewhat ochreous beneath; ^ , uncus single, very long 

 wide at the base, but somewhat laterally compressed above, having a narrow 

 stalk immediately beyond the base, whence it is lati rally compressed, down- 

 wardly dilated, and tapering posteriorly to a narrow and slightly upturned 

 gouge-shaped point ; lateral claspers rounded externally, with an angulated pro- 

 jection at about the middle of the upper edge, whence they taper posteriorly to 

 a narrow, slightly upturned obtuse point, reaching as far as the end of the uncus; 

 within these claspers, and projecting slightly beyond the angle at the middle of the 

 upper edge, are two spatulate appendages, or supplementary claspers, fringed, 

 • with hairs along their edges and about their surface. 9 with the ovipositor 

 strongly exserted, flattened at the base, and fringed at the extremity with simi- 

 lar hairs to those found on the supiiJementary claspers of the male.

Two males aud one female received from the late H. K. Morrison. 

 Without a careful examination of the ueuration aud genital segments this species 

 would undoubtedly have been regarded as a Butalis, lor although somewhat larger 

 than the ordinary forms of this genus ; it has almost exactly the shape of wings and 

 general appearance which distinguish it. The fore aud hind wings are, however, 

 somewhat narrower towards the apex.
